The A6 Annihilator (given its name from the SNES Teenage Mutant Ninja Turtles IV: Turtles in Time instruction manual) is a bun-shaped pod robot with tentacles and a laser turret.
In Turtles In Time they fire lasers at the Turtles, capturing them in a lasso-style. They are also dropped by Krang during his second boss fight.
